Research on bidding decision-making approach for construction enterprises based on group TOPSIS

This paper advanced a decision-making model aiming at the bidding decision-making problem of construction enterprises on the basis of group TOPSIS. First, based on the fact of policy-makers preference issues that existed in decision-making and in order to narrow and reduce the phenomenon of great error brought by decision-makers´ preference, this paper addressed an assumption that decision-makers were rational, and this paper formed a decision-makers position matrix; then, the multi-attribute decision-making integrated values given by group decision-makers to the bidding projects comprised a matrix, of which the entropy theory for data mining was adopted in this paper to determine the attribute weights; finally, the optimal decision-making conclusion was made based on TOPSIS method. Eventually, the feasibility and practicability of the model is verified by the example.
